Systems 5 and I do hereby declare the following to be a full, clear, and exact description of theinventiom'such as w ll enable others skilled in the art to which it'appertains to make and use the same.

My invention has for its object to provide an improved conveying, sorting, screening,

sacking-and distributing system especially adapted for use in handling potatoes in warehouses and, to this end, it consists of the novel devices and combinations of devices hereinafter described and defined in the claims. p v

In the accompanying drawings, which illustrate the invention, like characters indicate like parts throughout the several views.

Referring to the drawings: Figure 1 is a view partly inside elevation and partly in longitudinal vertical section, showing the receiving end of the improved system; some darts bein broken awa Fi 2 is an end elevation of the same; Fig. 3 is an end elevation. of the delivery end of the improved system with the distributing belt removed and some parts sh an enlarged scale; Fig. 4 is a detail view in perspective, showing the delivery end of one 5 is aplan system with the sack filling spouts removed, some parts being broken away; and Fig. 6 is a side elevation of the parts shown in Fig. 5, some parts being broken away, and some of the exposed parts being shown in vertical section.

The numerals 1 and 2 indicate, respecthe firstfloor and the basement of a warehouse. Located substantially in the same plane with the floor 1 is a scale plat form 3. A horizontally extended conveyer trough 4 issuspendedwithin the basement 2, by timbers 5, from the floor 1, at an eleva tion below the scale platform 3. An inclined spout 6-is rigidly secured to the scale platfor1n3 and its delivery end is arranged to deliver into the conveyer trough 4. A conveyer 7, comprising a pair of laterally spaced link belts 8 connected by a plurality 1wn in vertical section, on

of round iron slats 8?, is mounted in the trough 4, and thelink belts 8 run over front and rear pairs of alined sprocket wheels 9 secured, respectively, to a ,power shaft 10 and'an idle shaft 10? journaled in the sides of the trough 4. Q The upper runs of the link belts 8 are guided by rails 11 secured to the 1 sides of the conveyer trough 4, and the lower run of said belts travel over and are supported by the deck or bottom of the conveyer trough presently appear.

4, the purpose of which will A hopper or bucket 12,

for receivlngthe refuse, is suspended by a ibail 13 from the scale platform, directly under the receiving end of the conveyer trough 4. In one side of the hopper '12 is lmounted a gate 14 which slidably works be tween cleats 15 secured to said hopper. loperating rod 16 is secured. to the gate 14 and projects above the floor 1. This rod affords means by which the gate may be lifted, to dump the refuse from the hop- ;per Potatoes, after'being weighed on the scale platform 8, are dumped down the inclined spout 6 onto the conveyer slats 8 and hence carried by said conveyer to the delivery end of the conveyer trough, 4. Refuse, such as dirt and small potatoes, will be screened through the slats 8* and deposited on the deck of the conveyer trough 4. The lower run of the conveyer 7 working over said deck, in the directlon of the arrow marked on Fig 1,"'will scrape all refuse deposited thereoninto the hopper 12. The ends of the shaft 10 are extended outward of the conveyer trough 4 and journaled in bearings 17 mounted on the frame work 18 secured to X Mounted on one end of the shaft 10 are fast and loose pulleys 19 and 20, respectively, over either one of which runs a belt, not shown, for driving the conveyer 7. y

At the delivery end of the conveyer 7 is located a pair of reverselyextended sack fillin s cuts 21 arran ed to deliver to either. 6 2D side of the conveyer 7. To the delivery end of each spout 21 are secured-front and rear sack holding cleats The upper edges of the cleats 23 are inwardly anddownwardly beveled, to assistin holding sacks Z, the mouths of which are telescoped directly over the delivery endsof 'said spouts2l. Turn buttons 22 are pro- 22 and 23, respectively;

vided for clamping said sacks onto the'cleats 22, thereby completing the sack holding means, Hinged at 24-t0 the junction of the bottoms of the two spouts 21' is a swinging gate 25, adapted to be moved into positions to close either one of the two spouts 21.

Thi gate 25 also acts as an extension of the bottom of the spouts 21 which are open and onto which the potatoes are delivered from the conveyer 7. Reversely extended cables 26 are provided for operating the gate 25. To prevent bruising of. the

potatoes, the sidesof the conveyer trough 4c and the spouts 21 are, preferably padded and lined with any suitable material. c

Located adjacent to one side and at. the

delivery end of the conveyer trought is an elevator shaft27 which extends from the floor of the basement 2 through the floor 1.

Mounted in the elevator shaft 27 is an elevator not shown, for elevating the sacks Z when filled from the spout 21. Extending transversely of the delivery end of the conveyer trough 4, outward of the sack filling spouts 21, is a horizontally extended distributing, belt 71 mounted to] run over a driven roller 72 and a loose roller These rollers are journaled in later ally spaced side plates 78 which, together with the belt 71, afford atrough. Potatoes are delivered from the conveyer 7 to the distributing belt 71 over an incline spout 74, 'pivotally secured to the shaft 10'. To the trunnion of the roller 72 is keyed a bevel gear 75 with which meshes either one of a pair of laterally spaced bevel gears 76 keyed to a shaft 77 which is journaled in bearshipper collar 61. A

'ings 78 on a suitable support 79. To one end of the shaft 77 is keyed a pulley 80 over which runs a driving belt, not shown, and on the other end of theshaft shipper lever, not shown, may be applied to this collar 81, for moving the. gears 76 into and out of'mesh with the bevel gears 75. By these gears 76, the distributing belt 71 may be driven in either direction, at will.

Pairs of opposite gate openings 82 are 1 formed by cutting out sections of the side gates 83 which are hinged at 2 plates 73. Opposite gates 83 These cut-out sections afford 84 to the side are connected movement, by

Downwardly inclined discharge plates 7 3.

in pairs, for simultaneous links 85. I spouts 86 are attached to the side plates in positions to receive fronr the distributing belt 71 either at the ends thereof or through the front gate openings 82. By

turning'the gates 83 into alinement with the side plates 73, the gate openings 82 are closed and the passageway between the said side platesis opened, permitting potatoes to'be delivered by the distributing'belt 71 to either of the end I discharge spouts 86. When the gates 83 are turned into positions 77 is keyed a by the conveyer 7, the waste in indicated by full lines in Fig. 1 0, the gate openings leading to theside spouts '86 are open and one of each pair of said gates extends obliquely across the passageway between theiside plates 73, forming a con 'tinuation of one of the sides of theside spouts86 and also affording a scraperto tributing belt 71 through the gate openings 82leading to the side spouts 86. Thefree ends of the discharge spouts 86 will, in actual practice, be arranged to various bins within the warehouse. g 1 The operation of the improved system may be briefly stated as follows; v V

The potatoes hauled to the warehouse are first weighed on the scale platform 3 together with the vehicle,. to securethe gross weight. The potatoes are then dumped onto theconveyer 7 ,and carried thereby to the delivery end of'said conveyer. All dirt, rubbish, and small potatoes will be screened potatoes'roll down thespout 6, all rotten and defective ones may be thrown into the hopper 12. After the load of'potatoes is removed by the conveyer 7, the ve'hicle,.to-

gether with thewaste deposited injthe hopper 12, is again weighed to find the tare which. subtracted from the I gross weight, will give the net weight.

At" the delivery 'end of the conveyer 7, the potatoes may be. ,directed to the sacking spouts 21 byraising the spout 45 into an inoperative position,

:or they may be directed onto the sorting belt 71 by turning the spoutzla into the position indicated in Figs. 8 and 10. From the sort- ,ing belt71, the potatoes may be delivered to anyone of the several bins in'the warehouse by simply changing the position of the gates 83 and the direction of "travel of said belt, After each load has been removed the hopper 12, may be dumped.

All the parts of the improved system are so located as to take up very little room in the Warehouse and they are extremely easy ti..- operate, thus making'the handling of the potatoes an easy matter. By the use oftmy,

improved system, the cost of handling' p0 jtatoes in the warehouseis greatly reduced.

Potatoes arealso thoroughly screened while they arecarried on the conveyer 7, without relieving the farmer from walting his turn to unload.

defective pop y a O ly deliver into the conveyer, I

discharge the potatoes carried bythe disthrough the conveyer 7 and deposited on the deck of the conveyer trough l from which they are scraped, by the lower section of the conveyer 7 into the hopper 12 As the for the good potatoes. It is, of course, understood that this device may be used for handling all kinds of produce.
